i would read the data from a file that is outside your DocumentRoot. This prevents people from getting your password when the server should fail to run the JSP and deliver the sources.
Also if there is several people that are allowed to access this machine eg. via ftp, make an account especially for this file and let noone else access it.
Also a simple XOR encryption could already please your security admins.
Itīll be much harder if people have SSH / telnet / ?? connection. Do they?
